1. An underlayment adapted to receive and secure at least one heating element of a radiant heating assembly, comprising:

  • a base material defining an area and having a first side and a second side disposed opposite the first side;

    a first protrusion disposed on the first side of the base material, the first protrusion configured as a geometric shape comprising a top surface, a sloping surface, and at least two sides, wherein the sloping surface forms an obtuse angle with the top surface and slopes downwardly from the top surface to the first side of the base material, and one or more of the at least two sides includes an angular element receiving surface; and

    a second protrusion disposed on the first side of the base material and adjacent to the first protrusion, the second protrusion configured as a geometric shape having at least two sides, wherein one or more of the at least two sides includes an element receiving surfacewherein the element receiving surface of the second protrusion is offset from and facing the angular element receiving surface of the first protrusion forming an element receiving cavity therebetween, and further wherein a horizontal distance between the element receiving surface of the second protrusion and the angular element receiving surface of the first protrusion is greatest at a height that is closer to the first side of the base material than to the top surface of the first protrusion; and

    wherein the element receiving cavity is configured to contain at least one heating element of the radiant heating assembly.
